IMPRovEMENT IN ROQFING-TILES.

-Specification forming part of Letters Patent No. 147,061, datedFebruary 3, 1874 application file( November 28, 1873.

To all whom 'it may concern: y

Be it known that I, GAREY MANVEL, of

Rochester, in. the county of Monroe and State of New York, have inventeda new and Improved Tile and Cement Booting, of which the following is aspecitication:

My invention consists of molded tiles of ela y, glass, or othermaterial, having a raised rib on thie top along one edge, projectingbeyond the edge, for overlapping the margin of the next tile to coverthe joint, the lower side of the rib being fiat to correspond with theat surface of the tile, joined on with a slight space between the riband the tile, which is iilled with cement; and the lower end is providedwith a rabbet in the under side to overlap the end of the next tilebelow, the rabbet having a rise at one corner of the tile, under the ribat the edge, to receive the rib of the lower tile, the wall of theelevated portion of the rabbet being beveled to fit the outside form ofthe ribs, which are beveled at the corners, and the opposite corner ofthe tile, which is not ribbed, is notched to receive its portion of therib of the lower tile, said notch being also bev eled to suit the formof the rib. This joint is also secured by cement along the edge of therib which overlaps the unribbed side of the tile. Each tile is providedwith a little groove or gutter for carrying the water away from thejoint. The arrangement allows of having the joint-ribs in line from topto bottom of the roof, and is at the same time very simple'.

Figure l is a plan view of a number of tiles arranged together as on aroof according to -1ny invention. Fig. 2 is a section on the line .c x.Fig. 3 is a cross-section on the line y y; and F1g.4 is a cross-sectionon the line z, looking in the direction indicated by the arrow.

Fig. 5 is a detail, showing the cement joint clearly.

Similar letters of reference indicate corrcsponding parts.

A represents the body of the I tiles; B, the raised rib, extending from.end to end along' one margin, and projecting beyond to overlap themargin ofthe adjoining tile and cover the joint. G represents the rabbetin the lower end to overlap the margin of the upper end of the next tilebelow and cover the joint D. E represents the raised portion of therabbet under the rib B, whose wall F is beveled to suit the externalshape of the ribs; and G represents the notch in the corner not having arib to complete the space for the rib ofthe tile below. Both the jointsare cemented together,

as shown by the black lines H. I represents the groove in the uppersurface of the tile along the margin, which is overlapped by the rib tocarry oiil the water and prevent it from setting back in or against thejoint, to protect the cement from the water, and to prevent the waterfrom leaking through in case the cement gives way. The tiles are to befastened on the root1 by nails or screws, countersunk, and eovered ormade water-tight by cement.

Having thus described my invention, I claim las new and desire to secureby Letters Pat- A tile and cement roof made of tile having theoverlapping rib B along one edge, a groove, I, along the other edge, andthe rabbet C E and notch G in one end, arranged and conneeted togetheras described.
